NOISEELESS CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 643,134, dated February13, 1900. Application filed February 13, 1899. Serial No. 705,455. (Nomodel.)

To all 1071,0111 it may concern.- BeitknownthatI,IsRAELHOGELAND,acitizenof the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented a new Noiseless Car-Wheel, of which thefollowing is a specification.

My invention relates to car-wheels for all classes of coaches, sleepers,poultry, postal, and stock cars, cabooses, and freight cars onsteam-roads, as also cable, street, horse, and elevated-road cars.

The full nature of my invention will be 1111 derstood by theaccompanying drawings and the description and claims following.

In the drawings, Figure 1 is a central section through the tire alone.Fig. 2 is a central section through the body or center of the wheelwithout the tire. Fig. 3 is a central section through the wheel in itscomplete form. Fig. 4 is an elevation of the body or center of the Wheelon the side to which the tire is secured, the tire being removed. Figs.5, 6, and 7 are details of the cushions between the body or center andthe tire.

In detail, 1 is the tire of a wheel, which is made separate from thebody or center portion 6.

2 is an interior annular flange, and 3 is the interiorsurface of themain portion of the tire, and it is made inclined, as shown, so that theinternal diameter of the tire at a point back against the annular flange2 is less than the internal diameter at the outer edge of this mainportion of the tire. The purpose of this will appear hereinafter.

4 is a recess within the exterior flange of the wheel, making thediameter of the wheel at that point greater than the diameter elsewhere,as is clearly shown in Fig. 1.

5 shows a series of bolt-holes in the interior annular flange 2.

The tire is made out of gray iron, and its face is chilled. The body orcenter of the wheel is made out of gray iron. It is observed, therefore,that when the tire is worn a new chilled or hardened tire can be put inits place.

Turning now to the body or center of the wheel 6, an annular recess isprovided in which the interior annular flange 3 of the wheel is adaptedto fit. The interior surface of said recess forms a shoulder 7, andalong the exterior edge of said recess a rib 9 is located, forming aseat 8 therein for the cushion 16, as appears in Fig. 3. This depressionor seat holds the cushion-ring 16 tightly in place and prevents it fromspreading out under the extreme pressure to which it is subjected. Saidcushion-ring 16 is made, preferably, of paper. It is perforated with theholes 20 for the passage'ot' the rivets 17. The body or center of thewheel is provided with the rivetholes 13, through which said rivet-s 17extend. In this manner the tire is held on the body or center of thewheel.

The peripheral face 10 of the body or center of the Wheel is madeslightly tapering to permit the passage over it of the internal surface3 of the tire. The tapering form of these two engaging surfaces is somade as to permit the easy placing of the tire on the body or center ofthe wheel. The dimensions are preferably such that the tire will goreadily on the center or body of the wheel within onehalf inch of thelimit in the full-sized wheel, and then it is subjected to pressure toforce it into final position. This flaring form ofthe tire and taperingform of the center of the wheel is important also in view of the cushion15, which surrounds the peripheral center 10 of the body or center ofthe tire. The tire can easily be placed over said cushion-ring withouttearing it up or disturbing it or injuring it in any way. Said ring 15is preferably made of paper, leather, or asbestos. The latter materialis valuable in such position where the wheels are to be used on roughroads and are liable to overheating, where the roads have long grades toprevent the heat imparted by the brake-shoe to the tire beingtransmitted to the body or center of the wheel.

Along the outer edge of the body or center of the wheel aradially-extending annular flange 18 is provided that fits in the recess4 in the tire. Said flange has on it a rib 12 to form in the inner faceof said flange 18 a depression 11 to form a seat for the cushion-ring14. Said ring is preferably of the same material and character as thecushion-ring 16. The cushions 14 and 16 should be thick enough toprevent the outer edges of the ribs 9 and 12 from coming in positivecontact with the tire. It is observed that the cushion 15 must be outsomewhat in a curved form, as shown in Fig. 7, in order to fit properly011 the tapered surface of the body or center of the wheel.

From the foregoing description it will be plainthatlhaveinventedanoiseless car-wheel of Very simple yet very strong andefficient construction, and it is so formed with a sepa rable tire thatwhen said tire is worn a new tire can be put in its place and the wheelbe as strong as when it was first made. \Vhen the parts are beingriveted together the tire is pressed on or against the body or center ofthe wheel under many tons of pressure, so that when the rivets are allin place the wheel is substantially as solid and compact as if it wereintegral. Said parts may also be drawn together without a press by meansof bolts extending through the bolt-holes 5 and 13, and after the boltsare drawn tight with a wrench they can be singly removed and the rivetsinserted in their places one at 'a time. This may be done in anyordinary blacksmith or car shop.

The outside cushions 14 and 16 are prefer? ably of material and arrangedas shown, so that they will protect the main cushion from moisture.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A car-wheel comprising a body or center portion, a tire, means forsecuring the two parts together, and cushions between the parts, theengaging surface of one of the parts having a depression formed by anouter rib,

portion, and means forsecuring these parts together.

3. A car-wheel comprising a body or center portion with the peripheralsurfaces 7 and 10 and the flange 18 and the radial surfaces providedwith the ribs 9 and 12 forming depressions 8 and 11 therein, the surface10 being tapered as shown, cushions 1 1 and 16 fitting in thedepressions 8 and 11, the cushion 15 on the surface 10, a tire with theinternal flange 2, the inner tapering surface 3 and recess 4 to fitsnugly on the body or center portion of the wheel, said two portions ofthe wheel having the bolt-holes 5 and 13, and rivets or bolts forsecuring said parts together.

4. A car-wheel comprising a body or center portion, a tire, means forsecuring them together, a main cushion 15 between the parts and acushion on each side of the main cushion and clampedbetween radial faceson the tire and body, respectively and protecting the main cushion frommoisture.
